Phoenix police detectives are investigating a fatal collision involving a pedestrian and a motorcycle driver that happened Friday night in east Phoenix.   

Patrol officers responded to the area of 50th Street and McDowell Road just after 6 p.m.  Nov. 29 after being called to a collision involving a motorcycle rider and a pedestrian, according to a release from the Phoenix Police Department.

Officers and fire crews found Edroy McCormick, 36, suffering from critical injuries. He was taken to a hospital where he died.  

Detectives responded to the scene and learned McCormick was crossing McDowell Road outside any marked cross walks when he was struck by a west-passing motorcycle, according to the release.

The driver of the motorcycle initially left the area and came back while detectives were investigating, police said.

Detectives determined impairment was not a factor with the motorcycle driver during the investigation, and no arrest has been made. Charges may be made once detectives complete their full investigation, police said.
